In the story, Yor Forger secretly lives a double life.

In this Yor Forger costume guide, we’ll break down everything you need—from outfit and wig to makeup and contact lenses—so you can recreate the elegant yet deadly aesthetic that makes Yor one of the most popular Spy × Family cosplay choices today.

Who Is Yor Forger? Thorn Princess Assassin & Perfect Cosplay Character

Yor Forger is one of the central figures in Spy × Family, known for living a carefully balanced double life. Publicly, the Yor Forger character works as a quiet city hall clerk and becomes the adoptive mother in the unusual Forger family. Secretly, however, she is a highly skilled Spy x Family assassin, operating under the feared codename Thorn Princess. As the Thorn Princess, Yor carries out covert missions with incredible speed, precision, and strength, making her one of the most dangerous characters in the series.

Despite her lethal profession, Yor’s personality is surprisingly gentle and awkward in everyday life. She is elegant, polite, and often shy in social situations, which creates a charming contrast to her deadly abilities in combat. This dual nature—graceful yet terrifyingly powerful—is a big reason why fans love the Yor Forger Thorn Princess persona and why she stands out among anime characters.

For cosplay enthusiasts, Yor is an ideal character to recreate. Her design features an instantly recognizable silhouette: a sleek black assassin dress, long straight black hair, and striking crimson eyes. These bold visual elements make Yor Forger cosplay easy to identify even from a distance, while her iconic hairstyle and vivid red eyes give cosplayers the opportunity to capture the unmistakable look of one of anime’s most stylish assassins.

Yor Forger Costume Guide: Assassin Dress & Signature Accessories

The centerpiece of any accurate Yor Forger costume is the elegant yet dangerous assassin dress worn by Yor Forger in Spy × Family. Often referred to as the Yor Forger Thorn Princess outfit, the design perfectly reflects her dual identity—graceful on the surface but lethal underneath. The main piece is a sleek black halter dress that hugs the body and creates a sharp, elegant silhouette. A high side slit adds movement and drama to the look while also hinting at Yor’s agility and combat readiness. Gold rose ornaments placed near the neckline serve as a signature visual element that immediately distinguishes this outfit from other anime assassin designs.

Accessories are just as important when building a convincing Yor Forger dress cosplay. Yor’s look typically includes a gold rose headband, which sits near the side of her head and complements the rose details on the dress. She also wears long black gloves that extend above the elbow, adding both sophistication and a classic assassin aesthetic. Completing the outfit are her distinctive thorn-like gold earrings, a subtle reference to her feared codename, the Thorn Princess.

When these elements are combined—the halter dress, gold rose decorations, elegant gloves, and signature accessories—the result is one of the most recognizable costumes in modern anime. This cohesive design is why the Yor Forger Thorn Princess outfit remains one of the most popular and instantly identifiable choices for Spy × Family cosplay fans around the world.

Yor Forger Wig Tutorial: Long Black Hairstyle & Looped Bun Styling

The Yor Forger hairstyle is one of the most recognizable visual features of Yor Forger from Spy × Family. Her look features long, straight black hair that falls smoothly down the back, combined with soft side bangs that frame the face. What truly makes the style unique, however, are the distinctive looped low buns behind the ears, which give the hairstyle an elegant yet slightly unusual silhouette. This balance of simplicity and signature detail is why the Yor Forger hairstyle is instantly recognizable in cosplay.

When choosing a Yor Forger wig, a length of around 70–80 cm (28–32 inches) usually works best to match the anime’s long, flowing hair. The wig should have a natural straight texture with moderate density so it doesn’t appear too bulky. To recreate the iconic side loops, you can divide small sections of hair near the ears, twist them into circular loops, and secure them with hidden pins or small elastic bands. Some cosplayers also use lightweight foam inserts to help maintain the rounded shape.

For the most accurate Spy x Family cosplay wig, small styling details make a big difference. Applying wig wax or styling cream helps smooth flyaways and create the sleek anime finish seen in the series. Light trimming of the bangs can also help match Yor’s clean face-framing look. With the correct length, properly styled loops, and a polished finish, the Yor Forger wig becomes a key element in bringing the Thorn Princess to life.

Yor Forger Makeup Guide: Anime Assassin Look & Eye Makeup Tips

Creating the perfect Yor Forger makeup starts with a clean, porcelain-like base that reflects the elegant appearance of Yor Forger from Spy × Family. Begin with a smooth foundation that evens out the skin tone while maintaining a soft matte finish. Light contouring along the cheekbones and jawline helps define the face without looking overly dramatic. The goal is to achieve a refined, almost doll-like complexion that mirrors Yor’s calm and graceful presence.

The most important step in this Yor Forger eye makeup look is creating bold, expressive eyes. Apply red or crimson eyeshadow across the upper eyelid to echo Yor’s iconic eye color, then deepen the outer corners slightly for dimension. A sharp black eyeliner wing enhances the almond shape of the eyes, giving them a confident and slightly dangerous feel. Finish with long, dramatic lashes—either mascara or false lashes—to replicate the striking anime style often seen in anime assassin makeup designs.

For the lips, keep the color elegant but noticeable. A soft rose-red lipstick works perfectly to complement the red tones in the eye makeup while maintaining Yor’s refined aesthetic. Avoid overly glossy finishes; instead, choose a satin or semi-matte texture for a polished result. When combined with the signature hairstyle and costume, this balanced Yor Forger makeup look helps complete the deadly yet graceful presence of the Thorn Princess.

Yor Forger Eye Color: Best Red Contact Lenses for Accurate Cosplay

One of the most striking features of Yor Forger in Spy × Family is her vivid crimson red eyes. This intense eye color reinforces her identity as the deadly assassin known as the Thorn Princess. For cosplayers, matching the Yor Forger eye color is one of the most effective ways to make the character instantly recognizable. Even with the correct outfit and wig, the look can feel incomplete without the signature red gaze that defines Yor’s appearance.

To recreate this detail, many cosplayers use Yor Forger contact lenses designed specifically for anime-style characters. A great option is Red Manson Contacts, which feature a bold crimson tone that closely matches Yor’s eyes in the anime.

These lenses are designed to enhance the iris color while maintaining a dramatic anime aesthetic, making them ideal for red anime contacts cosplay looks like the Thorn Princess.

When choosing cosplay lenses, diameter and style also matter. A 14.0–14.5 mm diameter usually works best for Yor because it enlarges the eyes slightly without looking overly exaggerated. If you prefer subtle realism, choose natural-style red lenses with a softer gradient; for a more dramatic anime effect, full-pigment anime lenses create stronger visual impact in photos and convention lighting. For safety, always buy lenses from reputable brands, follow recommended wear times, clean them properly with contact lens solution, and never share lenses with others. With the right Yor Forger contact lenses, your cosplay instantly captures the unforgettable crimson stare of the Thorn Princess.
